RUKO Keyless Drill Chuck 1.5-13mm with 1/2 inch-20 UNF Mount

The RUKO Supra keyless chuck combines a full-metal body with a self-tightening 3-jaw design, giving you tool-free bit changes and a secure grip on diameters from 1.5 to 13 mm. Its 1/2"-20 UNF internal thread fits common cordless and impact drills, while the hardened steel jaws and dust protection keep it reliable in workshop conditions.

Highlights

• Keyless operation for fast bit changes without a chuck key
• Clamping range 1.5–13 mm covers most twist drills and accessories
• Self-tightening 3-jaw design increases grip force under load
• Full-metal construction for durability in demanding use
• 1/2"-20 UNF internal thread mounts directly to drill spindle

In daily use

Mount the chuck on your drill spindle and tighten by hand until the jaws close on the bit. The self-tightening mechanism keeps the bit secure during drilling, and the dust protection helps prevent debris from entering the mechanism. Suitable for cordless drills, impact drills, and stationary drills with a matching 1/2"-20 UNF spindle.
